Abstract
A clamp with a gas detection mechanism comprises a base, a workpiece, a clamping mechanism and the gas detection mechanism. The air inlet hole and the air outlet hole are arranged on the base and are communicated with each other. The air inlet is connected with the air detection mechanism, and air enters from the air inlet through the air detection mechanism. When the workpiece is placed on the base and clamped, the workpiece is attached to the base and has no gap, the air outlet hole is blocked, so that air entering from the air inlet hole cannot be discharged, and the air pressure detection unit detects that the air pressure is at a normal value. And when the workpiece and the base are not attached due to the existence of impurities and the like and a gap exists between the workpiece and the base, gas can escape from the air outlet hole to cause abnormal air pressure, and the external air pressure detection unit sends an alarm and stops the base to work when detecting the abnormal air pressure. Therefore, the purpose of detecting whether a gap exists between the workpiece and the base through gas detection is achieved.

The first and second mounting holes 12 and 13 are used for mounting the clamping mechanism 30. The two second mounting holes 13 are symmetrically arranged with the first mounting hole 12 as a symmetry point, and the centers of the two second mounting holes are on the same straight line. The positioning hole 14 and the positioning pin 15 are used to position the workpiece 20. It is conceivable that the positioning holes 14 and the positioning pins 15 may be changed in position and size according to different workpieces, which is per se prior art and will not be described further here. The axial direction of the air inlet hole 17 is perpendicular to the axial direction of the air outlet hole 16, and the air inlet hole 17 is communicated with the air outlet hole 16 and used for circulating air.
The workpiece 20 is provided with a positioning structure matched with the positioning hole 14 and the positioning pin 15, that is, the workpiece 20 comprises at least one workpiece positioning pin 21 and at least one workpiece positioning hole 22.
